BACKGROUND Technical Field

The present disclosure relates to transmission methods and devices in wireless communication systems, and in particular to a transmission scheme and device in non-terrestrial wireless communications.

Related Art

Application scenarios of future wireless communication systems are becoming increasingly diversified, and different application scenarios have different performance demands on systems. In order to meet different performance requirements of various application scenarios, it was decided at the 3rd Generation Partner Project (3GPP) Radio Access Network (RAN) #72th plenary meeting that a study on New Radio (NR), or what is called Fifth Generation (5G) shall be conducted. The work item of NR was approved at the 3GPP RAN #75th plenary meeting to standardize NR.

To ensure better adaptability to various application scenarios and requirements, the 3GPP RAN #75th plenary meeting also approved a study item of NR-backed Non-Terrestrial Networks (NTN) starting with R15 version and started a WI to standardize relevant techniques in R16. Propagation delays in NTN are much longer than in terrestrial networks.

Embodiment 3

Embodiment 3 illustrates a schematic diagram of a radio protocol architecture of a user plane and a control plane, as shown in FIG. 3 . FIG. 3 is a schematic diagram illustrating a radio protocol architecture of a user plane and a control plane. In FIG. 3 , the radio protocol architecture for a first-type communication node (UE) and a second-type communication node (gNB, eNB, or a satellite or aircraft in NTN) is represented by three layers, which are a layer 1, a layer 2 and a layer 3, respectively. The layer 1 (L1) is the lowest layer and performs signal processing functions of various PHY layers. The L1 is called PHY 301 in the present disclosure. The layer 2 (L2) 305 is above the PHY 301, and is in charge of the link between the first-type communication node and the second-type communication node via the PHY 301. In the user plane, L2 305 comprises a Medium Access Control (MAC) sublayer 302, a Radio Link Control (RLC) sublayer 303 and a Packet Data Convergence Protocol (PDCP) sublayer 304. All the three sublayers terminate at the second-type communication nodes of the network side. Although not described in FIG. 3 , the first-type communication node may comprise several protocol layers above the L2 305, such as a network layer (i.e., IP layer) terminated at a P-GW 213 of the network side and an application layer terminated at the other side of the connection (i.e., a peer UE, a server, etc.). The PDCP sublayer 304 provides multiplexing among variable radio bearers and logical channels. The PDCP sublayer 304 also provides a header compression for a higher-layer packet so as to reduce radio transmission overhead. The PDCP sublayer 304 provides security by encrypting a packet and provides support for handover of first-type communication node between second-type communication nodes. The RLC sublayer 303 provides segmentation and reassembling of a higher-layer packet, retransmission of a lost packet, and reordering of a packet so as to compensate the disordered receiving caused by Hybrid Automatic Repeat reQuest (HARQ). The MAC sublayer 302 provides multiplexing between a logical channel and a transport channel. The MAC sublayer 302 is also responsible for allocating between first-type communication nodes various radio resources (i.e., resource blocks) in a cell. The MAC sublayer 302 is also in charge of HARQ operation. In the control plane, the radio protocol architecture of the first-type communication node and the second-type communication node is almost the same as the radio protocol architecture in the user plane on the PHY 301 and the L2 305, but there is no header compression for the control plane.
